Frequently Asked Questions
How do I compress an image to exactly 20KB? +
Upload your image, switch to Exact KB Mode, type 20, and click Compress. The tool runs a binary search in your browser to hit exactly 20KB within 1KB accuracy — nothing is uploaded to any server.
Is this tool really no-upload? +

What image formats are supported? +
JPEG, PNG, WebP, AVIF, and HEIC (iPhone photos) are all supported. Output can be WebP, AVIF, JPEG, or PNG. HEIC files are automatically converted in your browser before compression.
